4 Claims. (Cl. 24-205) My invention relates to separable interlocking fasteners and particularly to` the attachment of the individual fastener members to the edges of 'flexible supports. A y

My invention aims particularly to provide means for anchoring individual fastener members in large numbers at small expense on the edges of flexible tapes without substantial distortion of the said fastener members during attach- The fastener members may be shaped from a suitable non-metallic material of the plastic class.

the fastener members maybe molded individually from phenolic condensation products such as bakelite. The fastener members, however, can not be attached to the tapes in the same way as metallic members for the reason that the clamping portions can not be bent after they are completely formed except by the application of heat which introduces many complications and is difficult to control.

My invention specically provides anchor or coupling members mounted in recesses in the fastener members and either piercing or engaged in some manner with the tape so as to hold the fastener members against movement along the edges of the tape. In the accompanying drawing I have shown for purposes of illustration, three specific embodiments of my invention. In the drawing:

Fig. 1 represents a general view of the fastener constructed according to my invention;

Fig. 2 is a cross-section through the fastener;

Fig. 3 is a perspective view of angindividual fastener member;

Fig. 4 shows a coupling pin;

Figs. 5, 6 and 7 illustrate a modification: and

Fig. 8 shows a still further modication.

'I'he fastener illustrated comprises a pair of ilexible supports herein fabric tapes i0, il, having, if desired, beaded edges I2. The fastening members herein shown conform in general to the shape 'of the fastening members in certain wellknown slide fasteners. Each member has' interlocking means in the form of a projection I3 .and recess it, and attaching means in the form of parallel'arms i5. 'I'he fastener members are4 as the fastener member and having a pointed end may have a wedge ilt or after it is inserted it may be stuck in place by means of solvent or cement. In the modified form shown in Figs. 5, 6 and 'I the anchor members 2| have serrated surfaces 22 which engage in the tape. These members may 3 be formed of the same non-metallic material as the fastener member or they may have a sheet metal serrated bottom anchored to non-metallic heads. In Fig. 8 there is illustrated a rivet 23 havingV a non-metallic head 2.4 which may be used 1 in the place of the pin I9.

While I have shown and described in this application three embodiments which my invention may assume in practice, it will be understood that these embodiments are only for the purposes 15 of illustration and description and that various other rforms may be devised within the scope of my invention as defined in lthe appended claims.

What I claim as my invention is:-

l. In a separable interlocking fastener the com- 20 bination of a flexible support, a series of bifurcated non-metallic fastener elements mounted astride one edge of the support, at least one of the bifurcations of each element having a recess therein, and non-metallic retaining means dis- 25 3. In a separable interlocking fastener the combination of a flexible support, a series of bifurcated non-metallic fastener elements disposed astride one edge of the support, each of the bifurcations having a recess therein, and non-metallic retaining means in each of said recesses in locking relation with said tape, said retaining means beng cemented to the fastener elements.

4. In a separable interlocking fastener the combination of a exible support, a series of bifurcated non-metallic fastener' elements disposed astride one edge of the support, at least one of the bifurcations of each element having a recess therein, and a non-metallic anchoring member disposed in said recess. said anchoring member having a roughened face held in locking relation with the support. the anchoring member being cementedto the walls of said recess.
